Addressing Example - Festo CPX-E-PN Translation Of The Original Instructions

Function
– The bus module counts as a module with 0 inputs and 0 outputs when the status bits and the I/O
diagnostic interface are deactivated.
– Activated status bits occupy 8 inputs.
– An activated I/O diagnostic interface occupies 16 inputs and 16 outputs.
– The inputs and outputs of different module types are assigned separately from each other.
Addressing is generally carried out by the higher-order controller (in cases where a SIEMENS higher-
order controller is being used).
